ProGuard rules for Conceal
ProGuard has the optimization phase and removes unused classes, fields and methods from your program code. After ProGuard shrinks and obfuscates code, short names like 'a', 'b', etc. are used as obfuscated names. Use the following ProGuard-style specification for your proguard-rules.pro file.
-keep,allowobfuscation @interface com.facebook.crypto.proguard.annotations.DoNotStrip
-keep,allowobfuscation @interface com.facebook.crypto.proguard.annotations.KeepGettersAndSetters
# Do not strip any method/class that is annotated with @DoNotStrip
-keep @com.facebook.crypto.proguard.annotations.DoNotStrip class *
-keepclassmembers class * {
@com.facebook.crypto.proguard.annotations.DoNotStrip *;
}
-keepclassmembers @com.facebook.crypto.proguard.annotations.KeepGettersAndSetters class * {
void set*(***);
*** get*();
